GAM kelp forest model Agder-Telemark, 2010

Region: The counties Aust-Agder and Telemark

Number of field observations: 1707

Field sampling years: 2005-2008

Prevalence: 43%

Presence / absences: 742/965

Method: GAM analysis in the statistical program language R, using "look up tables" and the "Grasp Extension" to transfer the predictions to ArcView GIS

Number of predictor variables: 6

Information about the predictor variables: curvature at coarse and detailed resolution (i.e. applying a 1025 and 125 m moving calculating window respectively) on a DEM with 25 m resolution; DEM, wave exposure, longitude and an optimal radiation index, all at 25 m resolution.

AUC internal: 0.88
